电动汽车的驱动电机要求有以下几个特点：宽广的恒功率范围，满足汽车的变速性能启动扭矩大，调速能力率高，区广瞬时功率大，过载能力强功率密度大，体积小，重量轻环境适应性高，适应恶劣环境能量回馈效率高根据驱动原理，电动汽车的驱动电机可分为以下4种：直流电动机在电动汽车发展的早期，很多电动汽车都是采用直流电动机方案。主要是看中了直流电机的产品成熟，控制方式容易，调速优良的特点。但由于直流电动机本身的短板非常突出，其自身复杂的机械结构（电刷和机械换向器等），制约了它的瞬时过载能力和电机转速的进一步提高；而且在长时间工作的情况下，电机的机械结构会产生损耗，提高了维护成本。

“触发”称得上数字示波器灵魂级的概念，如果没有合适的触发条件，波形观测也无从谈起。虽然很多工程师熟悉触发功能，但只知其表不知其里。如何深入理解触发呢？这篇ZDS示波器研发笔记在这里分享给大家。示波器在使用时首先要得到稳定触发的波形，这样才能保证后续的测量、等高级功能的可靠性。现在数字示波器的触发功能越来越强大，从常规触发，到协议触发，再到模板触发，越来越强大。但在基本的触发设置中，有些小细节的作用不可忽视，灵活掌握后，对使用示波器亦大有裨益。
